What would happen if the earth's rotation was faster or slower?
1 Answer
Days & nights would be shorter or longer, and our weight would be less or more.
Explanation:
If it was faster then one full rotation would take less than 24 hrs., thus making days & nights shorter. Our weight would be less, because as the Earth would rotate faster, it would exert more centrifugal force on us. The resultant force of the Earth's gravity and the centrifugal force would be less as gravity would remain constant but centrifugal force would increase. There would also be a temperature change as each hemisphere (Eastern and Western) would get less time to warm up from the Sun's rays.

The resultant force of the Earth's gravity and the centrifugal force would be more as gravity would remain constant but centrifugal force would decrease.
